  Megapov bug in JPEG image map ? (Message 1 to 3 of 3)

Hello all,

I try to make an image-map from a JPEG picture, but the following code
would consistently give me an error on the line "image_map..." 
in MegaPov 1.0 (non carbon, built 2 Jan 2003)/ Macintosh OS 9.1


#declare Ebump=function{ 
  pigment { 
    image_map {jpeg "book.jpg"
      map_type 1        
      interpolate 2     
    } 
  }
}


I have tried it with several JPEG pictures, but I always get the same
error message :
"Error : jpeglib : JPEG parameter struct mistmatch: library thinks size
is 464, caller expects 460"


Can anybody confirm/reproduce the problem on other platform or in
official POV-Ray ?


Stephane.

Not me, sorry. No problem with MegaPOV 1.0 whether or not #version is set to
unofficial MegaPOV 1.0 or just 3.5. Windows XP SP1 used here.

You are right, the Mac versions suffer from a compiler misconfiguration that
causes this problem.  It will be fixed in the next MegaPOV as well as in
POV-Ray 3.51.  This problem is Mac specific.
